The validation process can include printing a plurality of color patch chart(s) (or measurement sheets) 800 having a plurality of color patches (or calibration print stripes) 810. As disclosed herein, the plurality of color patches 810 on the color patch chart(s) (or measurement sheets) 800 are preferably read by the in-line spectrophotometer or colorimeter 411. The in-line spectrophotometer or colorimeter 411, for example, can be one or more inline color sensors (not shown), which are located in the paper path, and which feeds information to the CPU 401 for processing. The information received by the CPU (or processor) 401 from the in-line spectrophotometer or colorimeter 411 can be used to determine if one or more of the color patches 810 has failed, for example, at least one of the printed color patches 810 as read by the inline spectrophotometer or colorimeter 411 does not match a target color and/or the color quality is not within a desired target.

In accordance with an exemplary embodiment, in step 1230, the printer 40 can determine if instructions are received from the server 20 to conduct a calibration process. If the printer 40 receives instructions to conduct the color calibration process, in step 1240, the color calibration process is performed by the printer 40 based on the measured results and a target from the validation process. If, for example, the instructions do include a target, in step 1240, the color parameters of the printer 40 can be calculated and/or modified based on the measured data and a target sent from the server 20.

In accordance with an exemplary embodiment, if the printer 40 does not receive instructions from the server 20 to perform the validation process in step 1210, the process continues to step 1230. In addition, if the printer 40 does not receive instructions from the server 20 to perform the calibration process, the process continues to step 1250, in which additional and/or other processes can be performed. After step 1250, the process returns to step 1210.

FIG. 13 is a flow chart illustrating a validation process executed on a printer or printing device 40 according to an exemplary embodiment. As shown in FIG. 13, the step of conducting the validation process in 1310 can include in step 1320, printing the color patch charts 800 as shown in FIG. 8. In step 1330, the printed color patches 810 on the printed color patch charts 800 can be automatically measured using the in-line spectrophotometer or colorimeter 411 on the printer or printing device. In step 1340, the measured validation data from the printed color charts 800 is send to the server 20 from printer 40.

FIG. 14 is a flow chart 1400 illustrating a calibration process 1410 executed on a printer or printing device 40 according to an exemplary embodiment. As shown in FIG. 14, the calibration process can include in step 1420, printing of the color patch chart(s) 800 by the printer 40. In step 1430 the printed color patch chart(s) 800 are automatically measured by the in-line spectrophotometer or colorimeter 411. In step 1440, the printer 40 calculates (or modifies) the color parameter of the printer 40 based on the measured results of the printed color patches 810 and a target color. In step 1450, the printer reprints the color patch chart(s) 800 after calculating (or modifying) the color parameters on the printer 40. In step 1460, the reprinted color patch chart(s) 800 are automatically measured by the in-line spectrophotometer or colorimeter 411, and the measured data is sent in to the server 20 from the printer 40 in step 1470.

FIG. 15 is a flow chart 1500 illustrating a process for determining the best printing device 40 amongst a group or a plurality of printers 40 using a spectrophotometer in accordance with an exemplary embodiment, for example, in a marketplace 12. As shown in FIG. 15, in step 1510, each of the one or more buyers 32 can create a new account on the web portal (or management program 202) hosted on the server 20. The new account for each of the buyers 32 can include information related to the identity of the buyer, for example, business name, address, contact information etc. In addition, in step 1520, each of the sellers 42 can create a new account on the web portal (or management program 202) hosted on the server 20. The new account for each of the sellers 42 can include information related to the identity of the seller, for example, business name, address, contact information, etc.

FIGS. 16 and 17 are flow charts 1600 illustrating a process for determining, the best printing device amongst a group or a plurality of printers using a spectrophotometer in accordance with an exemplary embodiment. As shown in FIGS. 16 and 17, in step 1610, the buyer creates a new order (“new order”) for a print job, for example, as shown in FIG. 21, which is sent from the client or client computer 30 to the server 20. The new order can include, for example, default settings (static), for example, related to, price, schedule, location, and print quality. In addition, the new order can also include time of order preference (dynamic), time of order finishing capability, time of order date, time measurement date, and/or comments.

In accordance with an exemplary embodiment, in step 1620, the Processing unit 1 (or CPU) 201 on the server 20 searches for printing device (or printers) 40 that can handle the buyer's new order. In accordance with an exemplary embodiment, the server 20 will have a database of printers or printing devices 40, which can be searched. In accordance with an exemplary embodiment, the database of printers 40 can be stored in the management program 203 of the server 20. In step 1630, a determination is made if one or more printing devices 40 has been found that can execute the buyer's new order. If one or more printing devices 40 are found that can execute the buyer's new order, the process continues to step 1640, wherein the Processing Unit 1 201 of the server 20 filters (or determines) those printing devices 40 within the database of the server 20, which meet the buyer's location request. In step 1660, the Processing Unit 1 201 on the server 20 can make a determination, if the buyer's new request has a print quality requirement, for example, “High Print Quality”. If the new order does not require a certain print quality (for example, “High Print Quality”), the process continues to step 1700, where the Processing Unit 1 201 filters (or identifies) printing devices 40 that are available to execute the print job.

In accordance with an exemplary embodiment, if the new order does have a print quality requirement, the process continues to step 1660, wherein the CPU 201 filters (or identifies) those printing devices 40 that has an-inline spectrophotometer (or colorimeter) 411 and then proceeds to step 1700, where the Processing Unit 1 201 filters the printing devices 40 that are available to execute the job. For example, as set forth, if the buyer has requested a desired print quality, for example, a “High Print Quality”, the Processing Unit 1 201 will eliminate those printing devices 40 that do not have an in-line spectrophotometer 411. In addition, once the Processing Unit 1 201 has filtered or narrowed down the list of available printing devices 40, the Processing Unit 1 201 then searches for whether the printing device is available or not in step 1700. For example, a printing device 40 could have an in-line spectrophotometer 411, however, the printing device 40 could be down or offline, for example, because the printer 40 is waiting for parts and/or repairs. In accordance with an exemplary embodiment, step 1700 can be performed by querying the actual printing devices 40 (using, for example, Simple Network Management Protocol (SNMP protocol) and checking Management Information Base (MIB) value) to check for availability.

In accordance with an exemplary embodiment, once the Processing Unit 1 201 has identified or determined which printing devices 40 can perform the new order, in step 1710, the printing devices 40, which have been identified can bid on the new order. In step 1720, the Processing Unit 1 201 determines if any printing devices 40 meet the buyers request. As set forth, the next step is for the Processing Unit 1 to present to the remaining seller the job requirements (customer's price and schedule is not disclosed to seller). The seller will start to bid on this possible project. If in step 1720, one or more printing devices 40 meet the buyer's request, the process continues as shown in FIGS. 18-20.

However, if none of the seller's bids meet the buyer's request in step 1730, the process continues to step 1740, where a determination can be made if any of the bids are within an acceptable range. If none of the bids is, within an acceptable range, the process continues to step 1730, where a request can be made to the buyer to modify the order, and the process returns to step 1620. As set forth, if there are no sellers that meet the buyer's criteria for price and schedule, the Processing Unit 1 201 will request the buyer to adjust its parameters again like increase the price but keep schedule the same. The Processing Unit 1 201 can then go back to Step 1620 to re-do the search again.

Alternatively, if one or more of the bids are within an acceptable range, the process continues to step 1740, where the seller is requested to modify the bid, and the process returns to step 1710. As set forth, if the buyer's price and schedule are within the range acceptable by the seller (but does not meet the buyer's schedule and price requirements) then the Processing Unit 1 201 can ask the seller to change their bid to meet the buyer's job request, for example, in the sellers set-up as shown in FIG. 24.

As set forth in step 1630, the Processing Unit 1 201 will then perform a search on ail the sellers (and corresponding printers or printing devices 40) in the server's database that can handle the buyers print job requirements. For example, in accordance with an exemplary embodiment, the server 20 can search each sellers printer device 40 in the database to see which one has the finisher configuration that can meet the buyers job request. If no printing device 40 is found, the process continues to step 1670 to search for printing devices in other printer markets. If printing devices 40, for example, can be found in other markets, the process continues to step 1640. However, if no printings devices can be found, in step 1690, the buyer can be informed that the new order cannot be met or filled, i.e., printed.

In accordance with an exemplary embodiment, for example, if no printing devices 40 are available that meet the job's color quality requirements, the system and method as disclosed herein can be configured to allow the Processing Unit 1 201 to go outside its network as set forth in step 1670 of FIG. 16 to query other printing devices in other network environments. As set forth in step 1640, for example, once one or more printing devices 40 have been found, the number of printing devices 40 on the list can be further narrowed down by checking the distance of the seller to the buyer and seeing, if this meets the buyers distance criteria as set forth in the buy set-up as shown, in FIG. 23.

FIGS. 18-20 are flow charts 1800 illustrating a process for determining the best printing device amongst a group or a plurality of printers using an in-line spectrophotometer or colorimeter in accordance with an exemplary embodiment. As shown in FIGS. 18-20, if the buyer has requested high print quality, the CPU (Processing Unit 1) 201 of the server 20 can perform a color verification process to check if the printing device 40 can meet the higher print quality standards. For example, in accordance with an exemplary embodiment, the Processing Unit 1 201 can perform this by sending to each of the printing devices 40 a color test chart file and the actual print job file to each of the printing devices. Each of the selected printing devices 40 will RIP (and HOLD) the actual print job. Since the RIP process can take a long time, the RIP process can be processed in parallel, with the printing of the color test chart, such that the validation and/or calibration of the printing devices 40 can be performed without waiting for the RIP process to finish.

In accordance with an exemplary embodiment, each of the selected printing devices 40 will print the color test chart. However, in accordance with an exemplary embodiment, the Processing Unit 1 201 can be configured such that based on certain criteria and/or business concerns, only a portion of the plurality of the selected printing devices 40 will print the color test chart. When the color test chart is printed, the in-line spectrophotometer 411 will start measuring the color chart. The measurement data is sent back to the Processing Unit 1 201. The Processing Unit 1 201 will judge, based on the measurement results, which printing device meets the target measurement data. The target measurement data is sent by the buyer 32 upon making the print job order. If the buyer 32 does not include the target measurement data, then the Processing Unit 1 can use a default target measurement data.

In accordance with an exemplary embodiment, if there are some, printing devices 40 that meet the target measurement data, the Processing Unit 1 201 can send a request to the printing devices 40, which do not meet the target to delete the holding job. In addition, a final list of the printing devices 40 (or at least the terms of the sellers 42) can be presented toile buyer(s) 32. The Processing Unit 2 401 on the printing devices 401, which receives the request to delete the hold job, can then delete the holding job. If there are no printing devices 40 that meet the target measurement data, the Processing Unit 1 201 will ask at least one or more of the printing devices to run a color calibration. After running the color calibration, the process repeats as disclosed herein and the printing of the color charts.

In accordance with an exemplary embodiment, in the case, for example, that this is a Reprint function, the target measurement data is coming from a previous good print job measurement data. Once the Processing Unit 1 201 obtains a final list of sellers, the Processing Unit 1 201 can present the final list of sellers to the buyer by way of a graphical interface using map application software in order for the buyer to easily visualize the distance of the seller from the buyer. If the buyer's request includes a request for high print quality, the Processing Unit 1 201 will display a preview of the printed job along with the location, price and schedule the seller can offer. Based on the price, schedule, print quality, and location presented to the buyer, the buyer can then choose from among the different sellers. In accordance with an exemplary embodiment, the Processing Unit 1 sends the request to the Processing Unit 2 401 of the selected printing device 40 for printing of the print job.

In accordance with an exemplary embodiment, the detailed steps of the process as disclosed above is shown in FIGS. 18-20, and further described below. Initially, in step 1810 of FIG. 18, the Processing Unit 1 201 receives the new order (or print job) from the client 30 and determines if the print job requires a “High Color Quality”. If the print job does not require a “High Color Quantity”, the process continues to step 1820, where a determination is made, if the print job is probable to be reprinted, for example, the user has selected “Save Target for Reprint” 642 on the GUI 600. If the print job is not probable to be reprinted, for example, the user has not selected “Save Target for Reprint”, the process continues to step 1830, where it is determined, if the print job is a print job, which is to be reprinted, for example, a print job previously printed and saved in a memory of the server 20 and/or a printing device (or printer) 40. In accordance with an exemplary embodiment, for example, the “Reprint” function can determine that the CPU (or Processing Unit 1) 201 does not have to request the printing device 40 to print the test chart each time, especially, for example, if the printing device 40 has recently run a calibration job. If the print job is not a reprint, the process continues to step 1840, wherein the print job can be printed and/or undergo another process.

In accordance with an exemplary embodiment, if the print job is a probable for a reprinting, for example, the user is more likely than not or at least a 50% chance of being reprinted, and the user has selected. “Save Target for Reprint” 642, the process continues to step 1850, where the Processing Unit 1 executes a process by filtering those printing devices 40 that have an in-line spectrophotometer 411 from those printing devices 40, which do not have an in-line spectrophotometer 411. At this step, those printing devices 40, which do not have an in-line spectrophotometer (or colorimeter) 411 are discarded, and no longer considered. In step 1900, the Processing Unit 1 201 sends a color test chart and an actual job (for example, a print job) to a plurality of printing devices 40. In step 1920, the Processing Unit 2 401 of each of the plurality of printing devices 40 can begin the RIP process and holding (or storing) of the actual print job. In step 1930, each of the plurality of printing devices prints the color test chart 800 as disclosed herein. In step 1940, each of the plurality of printing devices 40 measures the color test chart and in step 1950 each of the plurality of printing devices 40 sends the measured results to the Processing Unit 1 201.

In accordance with an exemplary embodiment, in step 1960, the Processing Unit 1 201 receives the measured results from the printing devices 40 in step 1950, and judges, which printing devices of the plurality of printing devices 40 meets a color print target. In step 1970, the process determines if any of the plurality of printing devices 40 have met the color print target. In step 1972, for those printing devices 40, which do not meet the color print target, those devices are instructed to delete the hold job. Alternatively, in accordance with an exemplary embodiment, if a printing device receives instructions in step 1980, at least some of the one or more printing devices 40 can be instructed to run a calibration in step 2000.

In step 1970, if none of the printing devices 40 meet the color target, in step 1974, at least some of the plurality of printing devices can, be requested to run a color calibration.

In accordance with an exemplary embodiment, in step 980, each of the printing devices 40 may receive an instruction to run or perform a color calibration. If the printing device 40 does not receive an instruction to run a color calibration, the process continues to step 2010, where the printing device 40 may receive an instruction to delete the hold job. If the printing device 40 receives the instruction to delete the hold job, the process continues to step 2020, in which the printing device 40 will delete the hold job.

Alternatively, if the printing device 40 receives an instruction to run a color calibration in step 1980, in step 2000, the printing device 40 will run a color calibration. The process continues to step 2010, where the printing device 40 may receive an instruction to delete the hold job. If the printing device receives the instruction to delete the hold job, the process continues to step 2020, in which the printing device will delete the hold job.

In accordance with an exemplary embodiment, in step 2050, those printing devices 40 meeting the target color are presented to the buyer. In step 2060, the buyer can choose a seller from the list of printing devices 40 (or sellers 42), which are candidates for the print job. In step′2070, if a seller 42 is selected by the buyer 32, instructions can be sent to a selected printing device 40, i.e., destination printer or printing device 40 to print the job.

In accordance with an exemplary embodiment, in step 2030, a determination can be made for each of the one or more printing devices 40, if a print request is received. If the printing device 40 receives instructions to print the hold job (or print job), in step 2040, the print job is printed. Alternatively, if the printing device 40 does not receive an instruction to print the hold job or print, job, the printing device 40 does not print the job.

FIG. 21 is an example of a buyer set-up 2100 in accordance with an exemplary embodiment. As, shown in FIG. 21, the buyer set-up (or user interface) can include Default Settings 2110, which are static and do not change, which can include, for example, price, schedule, location, and print quality. In accordance with an exemplary embodiment, for example, the Default Settings are preprogrammed into the buyer set-up 2100. However, the buyer may also input dynamic or Time of Order Preferences, in which one or more the static setting can be changed at the buyer's request. For example, the price, location, and print quality can be changed and/or modified. In addition, finishing capabilities 2130, which can include, for example, cover insert, staple, binding, saddle stitch, perfect bind, ring bind, hole punch, duplex, etc. can be specified. The buyer set-up 2100 can also include Time of Order Data 2140, for example, which can include the file name and number of copies requested. In addition, Target Measurement Data 2150 and Comments 2160 can be added, which can include, for example, special requests.

FIG. 22 is an example of a seller set-up 2200 in accordance with an exemplary embodiment. As shown in FIG. 22, the seller set-up 2200 (or user interface) can include specific details about the printer or printing device 2210, for example, engine, model, engine speed (RPM), resolution (DPI), and finishing capabilities 2220. As set forth in the buyer set-up 2100, the finishing capabilities can include, for example, Cover Insert, Staple, Binding, Saddle Stitch, Perfect Bind, Ring Bind, Hole Punch, Duplex, etc. In addition, the seller set-up 2200 includes price and schedule 2230.

As shown in FIG. 21, the buyers can create an account in the marketplace to indicate their user preference in quality (print), cost, delivery (schedule) and geographic location relative to buyer's location. In return, the sellers can create an account as shown in FIG. 22 to indicate their printing device and their unique finisher capability. In accordance with an exemplary embodiment, once the system is set-up for buyers and sellers, then next step is when a buyer wants to purchase a printing service, buyer fills out each item as indicated on the buy set-up 2100. In accordance with an exemplary embodiment, the buyer may override the default preferences (static) 2110 based on the print job requirements. In accordance with an exemplary embodiment, any, preference left blank can revert to the default setting (static) 2110.

FIG. 23 is a flow chart 2300 showing illustrating a process for determining the best printing device amongst a group or plurality of printers using a spectrophotometer for a reprint job in accordance with another exemplary embodiment. In accordance with an exemplary embodiment, the Processing Unit 1 201 of the server 20 can receive input from the user via the graphical user interface (or GUI) 600 that the print job may be reprinted by selection of “Save Target for Reprint” 640. In step 2310, if the user selects “Save Target for Reprint” on the GUI 600 of the client 30, the process continues to step 2400, wherein image and color data is saved with the print job, as shown in FIG. 24.

In accordance with an exemplary embodiment, when it is determined that the user has selected the “Save Target for Reprint”, and it is probable that the user will request a “Reprint” or reprinting of the print job, the process includes determining at least one printer 40 which has an in-line spectrophotometer from the plurality of printers 40, determining at least one page to be measured as a target page, and sending the print job to the at least one printer 40 so that the determined page is measured as the target. In accordance with an exemplary embodiment, when it is determined that the print job is to be reprinted, and the at least one printer is a single printer, the Processing Unit 1 201 of the server 20 obtains measured data on the print job from the single printer, and stores the measured data in conjunction with the print job.

FIG. 24 is a flow chart 2400 showing a server 20 and a printer 40 illustrating a process for determining the best printing device amongst a group or plurality of printers using a spectrophotometer for a reprint job, and wherein the user has selected “Save Target for Reprint” on the GUI 600. As shown in FIG. 24, in step 2410, the Processing Unit 1 201 of the server 20 determines (decides) which pages of the print job should be saved for the target (or target data). In accordance with an exemplary embodiment, the step of determining the at least one page to be measured as a target as shown in step 2410, can include, for example, determining the at least one page based on density of a C, M, Y, K (CMYK) color model used in color printing. For example, the CMYK density (also known as “YMCK”), for example, the criteria can be a predetermined amount (or threshold) of coverage or area on a printed page, for example, at least a minimum amount of coverage or area of the printed page has color in accordance with a CMYK or YMCK color model. In addition, the criteria can be based on the number of pages or number of copies of a print job. For example, if the number of pages in the print job exceeds a predetermined number of pages, for example, 1000 pages, the 1^(st) page and the last page, which meet a certain criteria can be selected. In addition, if the print job exceeds a predetermined number of copies, for example, 1000 copies, pages from the 1^(st) copy and pages from the last copy, which meet a certain criteria can, be selected.

In accordance with an exemplary embodiment, for example, as shown in FIG. 25, a criteria for deciding if a page is to be printed for the target can be whether a page has pixel blocks 2510, 2520, corresponding to a predetermined combinations of Y, C, and K values (YMCK values). For example, a FOGRA39L chart, which is a characterization data set for color imaging or printing, has 1617 combinations of Y, M, C, and K values, and the user can set that a predetermined number of the 1617 combinations may be the predetermined combinations, for example, 20. However, if the 20 combinations are included in a single page, an in-line sensor cannot accurately measure the color when pixel blocks is too small (for example, only one pixel 2510. Therefore, in accordance with an exemplary embodiment, the criteria can include both YMCK value combinations and pixel block size.

For example, in accordance with another exemplary embodiment, when one of the YMCK value combinations is (Y, M, C, K)=(200, 200, 0, 0), this pixel block is OK (i.e., acceptable) on YMCK value but is not sufficient (or no good) on block size. Accordingly, for example, it would be desirable to have a pixel block, which is comprised of a plurality of pixel blocks 2520, which is acceptable on both the YMCK value and block size.

In step 2420, the Processing Unit 1 201, sends the print job including pages for the target to Processing Unit 2 401 of the printer 40. In step 2430, the Processing Unit 2 401 receives the print request from the Processing Unit 1 201 of the server 20. In step 2440, the process of receiving pages from the Processing Unit 1 201 on the Processing Unit 2 401 repeats (or continues) until all the pages are received by the printer 40. In step 2450, the printer 40 prints the page(s) received from the Processing Unit 1 201. In step 2460, the Processing Unit 2 401 determines if the printed page is a target, page. If the printer page is a target page, in step 2470, the target page is scanned and the color is measured by the in-line spectrophotometer 411. In step 2472, the image and the color values obtained by the in-line spectrophotometer are sent to the Processing Unit 1 201. If the printed page is not a target page, the printer 40 does not scan the page with the in-line spectrophotometer 411. The process repeats until each of the pages has been printed. In step 2490, the Processing Unit 1 201 receives the target data from the Processing Unit 2 401 and saves the images and color values with the job for use later for a “Reprint” job.

In accordance with an exemplary embodiment, in step 2310, if the print job is not probable for reprinting since the user has not selected “Save Target for Reprint” 640, the process continues to step 2320, in which the user is asked, if the print job is a “Reprint” 644 as shown in FIG. 6. If the user selects or does not indicate that the current print job is a “Reprint” 644, the process continues to step 1850 and proceeds for filtering of printers (or printing devices) 40 that have an in-line spectrophotometer 411 and printing of the print job as disclosed herein and shown in FIGS. 18-20.

Alternatively, if the user indicates that the print job is a “Reprint” 644 in step 2340, the target data previously saved in step 2400 is retrieved from the Processing Unit 1 201 of the server 20. In step 2350, a color quality target from the data is set and the process continues to step 1850 for filtering of printing devices that has an in-line spectrophotometer and printing of the print job as shown in FIGS. 18-20 and described herein.

In accordance with an exemplary embodiment, for example, when it is determined that the print job is a “Reprint” request, i.e., a setting of reprint has been requested by the user in the GUI 644, and the Processing Unit 201 of the server 20 has obtained the measured data on the print job from the two or more printers, the Processing Unit 1 201, can determine at least one candidate of a destination printer for the print job based on whether each of the two or more printers meets a predetermined print quality by comparing the measured data with a measured data on a prior job.

In accordance with an exemplary embodiment, when it is determined that the print job is a “Reprint” job, or has a setting of reprint 644, the at least one page measured as the target page can be determined based on which page has been measured as the target on a prior job. Alternatively, the at least one page measured as the target page can be determined based on a page count of the print job. In accordance with an exemplary embodiment, if the at least one page can be determined based on the pages that was previously measured for a prior job, or by conducting a validation and/or calibration process using the at least one page after starting the print job.

In accordance with an exemplary embodiment, if none of the two or more printers 40 meets a predetermined print quality, the Processing Unit 1 201 of the server 20 can determine at least one printer 40 from the two or more printers 40 and instruct each of the at least one printers 40 to conduct a color calibration process by using the in-line, spectrophotometer.
